Answer:

1) $\sqrt{569}$ 2) 8 3) 0.8 4) $\sqrt[10]{61}$

Step-by-step explanation:

The equation for pythagoream theorem is

a^2 + b^2 = c^2 (the caret "^" represents exponents)

Which equation is equivalent to sqrt x +11=15

Bas_tet [7]

Answer:

x=16

Step-by-step explanation:

We are given that

$\sqrtx+11=15$

we have to solve this equation for x

in order to do that we need to isolate x first

hence

subtracting 11 from both sides we get

$\sqrtx+11-11=15-11$

$\sqrtx=4$

Now we square on both sides we get

$(\sqrtx)^2=4^2$

$x=4 \times 4$

$x=16$

hence x =16
